I try to persist a knowledge session using the example code from Drools
5.5.0-Final Documentation. And I am stuck with following exception:
javax.persistence.PersistenceException: [PersistenceUnit:
org.drools.persistence.jpa] Unable to build EntityManagerFactory

Probably I did some configuration mistake. This is my setup:
1) I added following dependencies (via maven)
drools-persistence-jpa, btm (bitronix), h2 (database),
hibernate-entitymanager
2) I created a hibernate.cfg.xml, persistence.xml and jndi.properties file
(I put the jndi.properties file in resources/META-INF ( is this correct/
related to the error ?))
3) I made all my fact classes serializable
4) I added this code:
PoolingDataSource ds = new PoolingDataSource();
ds.setUniqueName( "jdbc/BitronixJTADataSource" );
ds.setClassName( "org.h2.jdbcx.JdbcDataSource" );
ds.setMaxPoolSize( 3 );
ds.setAllowLocalTransactions( true );
ds.getDriverProperties().put( "user", "sa" );
ds.getDriverProperties().put( "password", "sasa" );
ds.getDriverProperties().put( "URL", "jdbc:h2:mem:mydb" );
ds.init();
org.drools.runtime.Environment env =
KnowledgeBaseFactory.newEnvironment();
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.drools.persistence.jpa");
env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
env.set(EnvironmentName.TRANSACTION_MANAGER,
TransactionManagerServices.getTransactionManager());
env.set(EnvironmentName.GLOBALS, new MapGlobalResolver());
StatefulKnowledgeSession ksession =
JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);
This is my Hibernate config:
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate
Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>

<property
name="connection.driver_class">org.h2.Driver</property>
<property name="connection.username">sa</property>
<property name="connection.password">sa</property>
<property
name="connection.url">jdbc:h2:file:db/drools</property>
</session-factory>
</hibernate-configuration>
This is my persistence.xml:
